“Eos”, Thea Energy, Inc.’s first integrated fusion system, will utilize arrays of small, optimized planar coils that help to mitigate manufacturing complexity found in prior generations of the stellarator. To properly shape the magnetic fields necessary for plasma confinement, Eos will require hundreds of these planar coils; Thea Energy’s ability to reliably and quickly produce them will be...
A high-sensitivity inductive coil for detecting the Haas-van Alphen oscillations of magnetic materials or calibrating magnetic field was fabricated. The coil contains part A and part B which are well compensated in applied external fields with opposite winding directions. Fabrication of a high density (>1000 turns) pick-up coil within a small sample space (diameter~3mm) is challenging....
The background magnets of the superconducting conductor test facility (Super-X) are composed of CICC-wound superconducting coils, weighing approximately 100 tons, and are actively cooled using supercritical helium. During the cooling process, fluctuations in the chiller's power and the complexity of heat transfer may cause deviations from the designed cooling process. These factors hinder the...
The analysis and calculation of magnetic fields serve as the cornerstone for magnet design. In scenarios requiring intricate spatial magnetic field configuration optimization, high-throughput analytical computations are often necessary, posing significant computational cost challenges to existing finite element method (FEM)-based approaches. In recent years, surrogate model computations...
High-temperature superconducting (HTS) generators cooled by liquid hydrogen are being researched and developed, with a 6kA-class assembled conductor required to superconduct the field winding of a 600 MW-class generator. The development target was a conductor consisting of 9 HTS wires in a thiree-layer structure with a 5 mm diameter former. To verify the current capacity of the assembled...
The development of multi-filamentary high-temperature superconducting (HTS) tape represents a significant research direction for the advancement of future applications, largely due to its lower AC loss. The AC loss characteristics of the multi-filamentary structure have been the subject of extensive experimental and finite element simulation studies. Nevertheless, there remains a research gap...
High-temperature superconducting (HTS) coils are widely utilized in magnet applications due to their superior performance in compactness and energy efficiency. Traditionally, the critical current (Ic) of HTS coils has been measured using the 100 μV/m criterion, adopted from the international standard for second-generation HTS wires. However, as discussed in previous research, this criterion...
Under pulsed high magnetic fields, the interaction between the magnetic field and the spin of a material provides a unique opportunity to explore various magnetic properties, such as magnetization, dielectric polarization, and magnetostriction. These properties are critical for characterizing the diverse phase transitions that materials undergo. Among the measurement techniques available,...
